Rust Web Development with Rocket

By: Karuna Murti

Overview of this book

Looking for a fast, powerful, and intuitive framework to build web applications? This Rust book will help you kickstart your web development journey and take your Rust programming skills to the next level as you uncover the power of Rocket - a fast, flexible, and fun framework powered by Rust. Rust Web Development with Rocket wastes no time in getting you up to speed with what Rust is and how to use it. You’ll discover what makes it so productive and reliable, eventually mastering all of the concepts you need to play with the Rocket framework while developing a wide set of web development skills. Throughout this book, you'll be able to walk through a hands-on project, covering everything that goes into making advanced web applications, and get to grips with the ins and outs of Rocket development, including error handling, Rust vectors, and wrappers. You'll also learn how to use synchronous and asynchronous programming to improve application performance and make processing user content easy. By the end of the book, you'll have answers to all your questions about creating a web application using the Rust language and the Rocket web framework.

Implementing GET user

Let's look at the steps to implement this:

  1. We'll start with the basics by implementing the get_user() function in src/routes/user.rs:
    #[get("/users/<_uuid>", format = "text/html")]
    pub async fn get_user(mut _db: Connection<DBConnection>, _uuid: &str) -> HtmlResponse {
        todo!("will implement later")
    }

Before we implement get_user(), we want to prepare the other routines that we will use. For example, we want to return HTML, so we need to create a const of &'static str in the same src/routes/user.rs file as our HTML template.

  1. We will create two separate instances of const so we can insert different contents between the HTML prefix and suffix:
    const USER_HTML_PREFIX: &str = r#"<!DOCTYPE html>
    <html lang="en">
    <head>
    <meta charset="utf-8" />
    <title>Our Application User</title>
    </head&gt...
